    摘要: A preparation method for a power semiconductor device includes: providing a lead frame containing a plurality of chip mounting units, one side edge of a die paddle of each chip mounting unit is bent and extended upwardly and one lead connects to the bent side edge of the die paddle and extends in an opposite direction from the die paddle; attaching a semiconductor chip to the top surface of the die paddle; forming metal bumps on each electrode at the front of the semiconductor chip with a top end of each metal bump protruding out of a plane of the top surface of the lead; heating the metal bump and pressing a top end of each metal bump by a pressing plate forming a flat top end surface that is flush with the top surface of the lead; and cutting the lead frame to separate individual chip mounting units.
